Request to Amend Application and Response to DSDIP's Information Request · MCU14/0009

provision for on-site vehicular manoeuvring space to safely enter and exit the site
regardless of any vehicles queuing at the petrol bowsers.

2.   The applicant is to demonstrate that visibility at the proposed/existing access point
     achieves the Safe Intersection Sight Distance in the Department of Transport and
     Main Roads’ Road Planning and Design Manual (RPDM) and relevant sections of the
     AUSTROADS Guide to Road Design, Part 4A – Unsignalised and Signalised Intersection
     for a 70km/h design speed (to suit the posted speed of 60km/h).

     This must be demonstrated based on the physical survey and detailed on the plans
     certified by an appropriate Registered Professional Engineer Queensland (RPEQ) or
     Registered Surveyor.

In response to Item 2 of DSDIPs Information Request, DSDIP are advised that due to the
location and formation of the existing on-site service station, the current access
arrangement available to the site will not be altered to facilitate the proposed
development. Keith and Christina Rolton have owned the site for 13 years, and confirm a
zero accident history with regard to vehicles entering and exiting the site.

Due to the nature of the proposed use, resulting from the amendment to the application
from a Shop (Type 2 Retail Business) to Light Industry (Type 2 Industrial Business),
limited customer access will be generated by the proposed development, with
employee/staff traffic being the primary users accessing the site. Accordingly, the existing
access configuration available to the site provides optimal access opportunity to and from
the site when considering the site’s corner lot configuration, existing and proposed on-site
uses and road order hierarchy.

3.   The applicant is requested to provide a Stormwater Management and Design (water
     quantity and quality) report that demonstrates that the proposed development
     addresses potential stormwater impacts on the state-controlled road network. In
     particular, the applicant is to demonstrate that the proposed installation of water
     tanks will mitigate any increase to drainage on Kin Kin Road and will mitigate any
     increase in the width of flow in the kerb or encroach onto the road.

     The Stormwater Management Design must:
     (a) Be certified by a Registered Professional Engineer Queensland (RPEQ)
     (b) Be prepared in accordance with the department’s Road Drainage Manual and the
         Environmental Protection Act 1994 and Environmental Protection (Water) Policy
         2009.
     (c) Demonstrate that the management of stormwater (quantity and quality) post
         development can achieve a no worsening impact (on the pre-development
         condition) in accordance with the design criteria in the department’s Road
         Drainage Manual. Stormwater management for the proposed development must
         ensure no worsening or actionable nuisance to the state-controlled road network
         caused by peak discharges, flood levels, frequency/duration of flooding, flow
         velocity, water quality, sedimentation and scour effects.
     (d) Ensure the following are addressed, where applicable:
         # All relevant legal points of discharge for the development site are identified. No
         new discharge points for stormwater will be permitted on state controlled roads;
         # Overland flow paths are identified and hydraulic conveyance is maintained on
         the site as part of the proposed development;
         # Flood storage capacity is maintained on the site as part of the proposed
         development;
         # The adverse impacts from sheet flow on the state-controlled road network are
         prevented;
